Flyback duty cycle
Did you know?
WebA flyback converter has two operation phases, tON and tOFF, which are named after and controlled through the MOSFET’s switching states. During tON, the MOSFET is on and current flows from the input through the primary inductor, linearly charging the coupled inductor and creating a magnetic field around it (see Figure 1.b). WebOct 25, 2024 · This is because at each turn-on event, you store energy in the primary inductance of the flyback transformer and, at the switch opening, this energy has to go somewhere. If there is no load to absorb …

Webferred to as the duty cycle, D. The proportion of time that the primary FET is on results in a pulse train voltage of varying density across the primary of the transformer, V PRI. This voltage waveform is then coupled to the secondary side of the transformer due to the magnetic flux coupling properties of a transformer. WebFigure 1 shows a detailed 60-W flyback schematic, operating at 250 kHz. The duty-cycle is selected to be 50 percent maximum at the minimum input voltage of 51 V and maximum …
